ObjectiveTo investigate the effect of anisodamine on the expression of connexin 43 (Cx43) in swine ventricular myocardium after resuscitation from cardiac arrest.Methods The experiment was conducted on healthy pigs, and they were randomly divided into three groups, namely sham group, epinephrine group (control group) and anisodamine group (experimental group, animals were resuscitated combined with injection of 0.4 mg/kg of anisodamine), with 5 pigs in each group. Model of ventricular fibrillation was reproduced by alternating current challenge, and cardiopulmonary resuscitation (CPR) was performed 8 minutes after cardiac arrest. Left ventricular myocardium was harvested at 24 hours after restoration of spontaneous circulation. The expression and distribution of Cx43 were observed by immunofluorescence, Cx43 mRNA expression was assessed with reverse transcription-polymerase chain reaction (RT-PCR), and the protein expressions of Cx43 and phosphorylation of Cx43 (p-Cx43) were analyzed by Western Blot.Results The positive expression of Cx43 in ventricular muscle was distributed uniformly, mostly at the end-to-end linkage of myocardial cells, with a few side-to-side linkage in sham group. The positive expression of Cx43 in control group was significantly weaker than that in the sham group, and the signal intensity was significantly declined (4.35±2.10 vs. 10.02±3.66,P< 0.01). The positive expression of Cx43 at the end-to-end linkage and side-to-side linkage was irregular in experimental group, and the signal intensity was obviously higher than that in the control group (7.91±2.54 vs. 4.35±2.10,P< 0.05), but it was significantly weaker than that in the sham group (7.91±2.54 vs. 10.02±3.66,P< 0.05). For control group and experimental group, the Cx43 mRNA and protein expressions were significantly lower than those of the sham group [Cx43 mRNA (A value): 0.32±0.05, 0.32±0.03 vs. 0.48±0.07; Cx43 protein (A value): 0.43±0.03, 0.50±0.07 vs. 0.65±0.04, allP< 0.01], and there were no significant differences between experimental group and control group (allP> 0.05). The p-Cx43 protein expression of control group was significantly lower than that of the sham group (A value: 0.22±0.03 vs. 0.37±0.06,P< 0.01), and it was significantly higher in the experiment group than that in the control group (A value: 0.29±0.07 vs. 0.22±0.03, P< 0.01), but there was no significant difference with the sham group (P> 0.05). No significant difference in p-Cx43/Cx43 was found among sham, control, and experiment groups (0.57±0.09, 0.51±0.05, 0.58±0.06, all P> 0.05).ConclusionAnisodamine can improve the abnormal expression of Cx43 in ventricular muscle of pigs with cardiac arrest, which may be related to the protection effect of anisodamine on cardiac conduction.

Non-coding RNAs ( ncRNA ), including ribosomal RNA( rRNA), transfer RNA( tRNA), MicroRNA ( miRNA), long noncoding RNA(lncRNA) and small nucleolar RNA(snoR-NA), are a class of RNA that have multiple functions and are not translated to proteins. MicroRNA and lncRNA are involved in the injury, remodeling and aging of blood vessels, and it is necessary to understand the regulatory roles of MicroRNA and lncRNA in these processes. It is reported that MicroRNA and lncRNA are not only participated in the regulation of oxidative response, inflammation, cell proliferation and migration, and phenotype transition, they are also involved in the regulation of gene expression by conducting different mechanisms, including transcriptional regulation, post-transcriptional modification and chromatin remodeling. These aspects of regulation by MicroRNA and lncRNA are related to cardiovascular diseases, such as ath-erosclerosis, hypertension, myocardial infarction, stroke, pul-monary hypertension and diabetes, and thus provide a new way for genetic diagnosis and therapy of cardiovascular diseases.

When senescence induction is based on DNA damage, senescent cells display a unique phenotype, which has been termed “senescence-associated secretory phenotype”( SASP ) . SASP, including proinflammatory cytokines, growth factors, chemokines, matrix remodeling enzymes and other cytokines, may be an important driver of chronic inflammation and therefore may be part of a vicious cycle of inflammation, DNA damage and senescence. Senescence-associated secretory products released by such cells can affect the neighboring cells and further exacer-bate their regenerative capacity. SASP is associated with many chronic age-related diseases.

BACKGROUND:The osmotic tissue expander is a self-fil ing device consisting of an osmotic active hydrogel which is made of vinylpyrrolidone and mehtylmethacrylate. It can absorb body fluids and swel up gradual y after embedded.
OBJECTIVE:To explore the short-term and long-term regular patterns as wel as histocompatibility of the osmotic tissue expander in vivo.
METHODS:A self-control design was carried out in Wistar rats by embedding the osmotic tissue expander and high-density polyethylene into each side of their spinal column subcutaneously. Wound healing, tissue expansion and inflammatory reaction were detected and compared at different periods after operation.
RESULTS AND CONCLUSION:Al the wounds got primary healing. The device expanded fastest at week 1 after the implantation. After being enlarged to about nine times that of the initial size at week 4, the expander slowed down its swel ing. It reached its ultimate volume at week 12 which was about 10 times as big as that of the initial one. Then it remained almost the same size until the end of our design. Pathological sections showed that the inflammatory reaction of osmotic-tissue-expander-group had no significant difference from that of the control group (P>0.05). These findings suggest that osmotic tissue expander has a slow-lasting swel ing ability and good histocompatibility.
